Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 52,212,155, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 52,212,155 | |
| -1 | -52,212,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,212,155.
Example:
1 x 52,212,155 = 52,212,155
and
-1 x -52,212,155 = 52,212,155
Notice both answers equal 52,212,155
With that explanation out of the way, let's continue. Next, we take the number 52,212,155 and divide it by 2:
52,212,155 ÷ 2 = 26,106,077.5
If the quotient is a whole number, then 2 and 26,106,077.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 52,212,155 | |
| -1 | -52,212,155 |
Now, we try dividing 52,212,155 by 3:
52,212,155 ÷ 3 = 17,404,051.6667
If the quotient is a whole number, then 3 and 17,404,051.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 52,212,155 | |
| -1 | -52,212,155 |
Let's try dividing by 4:
52,212,155 ÷ 4 = 13,053,038.75
If the quotient is a whole number, then 4 and 13,053,038.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 52,212,155 | |
| -1 | 52,212,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 73 | 265 | 365 | 2,699 | 3,869 | 13,495 | 19,345 | 143,047 | 197,027 | 715,235 | 985,135 | 10,442,431 | 52,212,155 |
| -1 | -5 | -53 | -73 | -265 | -365 | -2,699 | -3,869 | -13,495 | -19,345 | -143,047 | -197,027 | -715,235 | -985,135 | -10,442,431 | -52,212,155 |
